After the effective date of this Act all contracts for the sale of a dwelling structure may be recorded or registered with the recorder or the Registrar of Titles in the same manner as a deed or other document relating to the title of the real estate to be sold. Any provision in a contract for the sale of a dwelling structure which forbids the contract buyer to record the contract or provides that recording shall not constitute notice or provides for any penalty for recording is void.
